That is, the second separable bottom end insertion section 150 also has the same recess 132 as the second separable bottom end insertion section 130. Similarly to the second separable bottom end insertion section 140, the second separable bottom end insertion section 150 is formed by fixing the box 131 to the tape 31 without the second reinforcing strip 22 and the third connecting part 23.

L'invention porte sur une fermeture à glissière (100) comprenant : une paire de première et seconde demi-chaînes de fixation (30A, 30B) ; au moins une fermeture à glissière (40) ; et un outil d'ouverture/ajustement en résine (1). L'outil d'ouverture/ajustement (1) comprend : une première partie d'ouverture/ajustement (10) qui est disposée au niveau de la première demi-chaîne de fixation (30A) ; et une seconde partie d'ouverture/ajustement (20) qui est disposée au niveau de la seconde demi-chaîne de fixation (30B) et qui peut être accouplée à la première partie d'ouverture/ajustement (10) ou désaccouplée de celle-ci. La première partie d'ouverture/ajustement (10) comprend : une broche d'insertion (11) ; une première partie de ligne de renforcement (12) qui est disposée à distance de la broche d'insertion (11) ; et une première partie d'accouplement (13) et une seconde partie d'accouplement (14) qui assurent l'accouplement entre la broche d'insertion (11) et la première partie de ligne de renforcement (12). L'épaisseur (T2) de la seconde partie d'accouplement (14) est inférieure à l'intervalle minimum (T1) entre une plaque d'aile inférieure (44) et une plaque d'aile supérieure (43) de la fermeture à glissière (40).
